What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Introduction: Myocardial ischemia/reperfusion (I/R) injury is a leading cause of cardiac dysfunction. Circular RNAs (circRNAs) are involved in the pathogenesis of myocardial I/R injury. However, the functions and underlying mechanisms are unclear. The present study determined the role of circ-RHOJ.1 in regulating myocardial cell proliferation and apoptosis after I/R injury. Material and methods: Myocardial cells isolated from Sprague-Dawley rats were identified with an immunofluorescence assay using cardiac troponin T antibody. Expression of circ-RHOJ.1, miR-124-3p and neuregulin-1 (NRG1) mRNA was assessed with real-time quantitative polymerase chain reaction. NRG1 protein expression was evaluated with western blot and immunofluorescence assays. Dual-luciferase reporter assay was performed to confirm interaction between miR-124-3p and circ-RHOJ.1, and miR-124-3p and NRG1. Effects of circ-RHOJ.1 overexpression or miR-124-3p inhibition on cell proliferation and apoptosis were evaluated using cell counting kit (CCK)-8 assay and flow cytometry. Cytokines levels were analyzed with an enzyme-linked immunosorbent assay. Results: Myocardial cells were successfully isolated and had down-regulated expression of circ-RHOJ.1 and NRG1, and up-regulated expression of miR-124-3p after I/R injury. circ-RHOJ.1 acted as a sponge for miR-124-3p, and NRG1 served as a target gene of miR-124-3p. circ-RHOJ.1 overexpression or miR-124-3p inhibition increased interleukin (IL)-10 levels and reduced IL-2, IL-6, and tumor necrosis factor-α levels in myocardial cells after I/R injury. Functional assay results illustrated that circ-RHOJ.1 overexpression or miR-124-3p inhibition enhanced proliferation and inhibited apoptosis of myocardial cells after I/R injury. Conclusions: Circ-RHOJ.1 served as a molecular marker of myocardial I/R injury via regulation of miR-124-3p and NRG1 expression.
